Many SMTP servers include the IP address of the sender in the headers (usually the Received header). Just look around, you'll be surprised.

- rufugee 12y agoUsing webmail would defeat that, though, right?
- encoderer 12y agoNot if the webmail implementation passes-on your IP, which it should if you believe Spam is a bigger issue than email sender privacy. Basically, if a webmail service doesn't pass along your IP, there would be no way for recipient networks to ever block a flood of unwanted email because they could never blacklist, say, yahoo.com. I read something about this lately... maybe from Paul Buchheit?
- cataflam 12y agoDepends on the webmail. Some do, some don't. Easy enough to test for yourself beforehand though.
